The exact bending solutions of moderately thick rectangular plates with two opposite sides simply supported are derived based on the symplectic geometry method.

The basic equations for the plates are transferred into Hamilton canonical equations. Then the whole state variables are separated.

The Kantorovich variational method was used in this study to solve the flexural problem of Kirchhoff-Love plates with two opposite edges x=±a/2 clamped and the other two edges y=±b/2 simply supported, for the case of uniformly distributed transverse load over the entire plate domain.

This paper presents a numerical analysis procedure, called spline semidiscretization procedure, for the unified analysis of orthotropic and/or isotropic thin plates and shallow shells of rectangular projection with the two opposite edges in the y direction simply supported.

The sine and cosine functions may thus be employed as the displacement trial functions in the y direction. In this chapter, vibrations of isotropic rectangular plates have been analyzed by applying the wave propagation approach. The plate problem has been expressed in integral form by considering the strain and kinetic energies.

Buckling of Rectangular Plates Under Inplane Shear Load. A method for the numerical analysis of rectangular plates based on Mindlin's theory is presented. Any two opposite edges are assumed to be simply supported in the present analysis. A variety of boundary conditions including the mixed and the nonhomogeneous types can be specified along either of the remaining two opposite edges.

For rectangular plates, Navier in introduced a simple method for finding the displacement and stress when a plate is simply supported. The idea was to express the applied load in terms of Fourier components, find the solution for a sinusoidal load (a single Fourier component), and then superimpose the Fourier components to get the solution for an arbitrary load.

New approach to static analysis of thin non-rectangular arbitrarily loaded plates, called the macroelement method, has been developed in this paper.

Macroelement is a rectangular plate which entirely contains real plate. The mathematical model of macroelement was built. The equilibrium equations are performed for macroelement and boundary conditions are written on the line corresponding to Cited by: 1.

Preface Since the publication of the first edition of this book, the application of the theory of plates and shells in practice has widened considerably, and some new methods have been introduced into the theory.

To take these facts into consideration, we have had to make many changes and additions. The principal additions are (1) an article on deflection of plates due to transverse shear, (2.

Since one of two opposite edges is simply supported and another is clamped, numbers of mode half waves take values and. The numerical procedure for determining natural frequencies is the same as in the case of clamped plate.
